The media-room spec — Sun Zero's heaviest liner construction, built for zero-glow rooms and serious day sleeping.
Sun Zero's 'Theater Grade Extreme' is the brand's maximum spec: a dense face fabric over a full blackout liner, sold as 2-pack panels, engineered for the home-theater use case where any glow ruins the picture — which is exactly the spec a day sleeper wants. It edges the H.VERSAILTEX on light-stopping consistency across colorways and comes from a 40-year US window brand, at a slightly higher price and with more conventional styling.

How our prices work
We show the price at our recommended retailer as at our last check of that offer (2026-10-11) and the manufacturer's list price for comparison. Amazon prices come from Amazon's own product data service and are refreshed twice a day; each one shows the date and time Amazon gave it, and one older than 24 hours is replaced by “Check price”. Other retailers' prices are checked by hand and show the date of that check. Retail prices move constantly, so the price on the retailer's own page at checkout is the one that applies.

Frequently asked questions
Theater grade vs regular Sun Zero?
Sun Zero sells tiers — 'room darkening' (~95%), 'blackout' (~99%), and this 'Extreme 100%' liner build. The tier naming is actually honest; buy Extreme for sleep-critical rooms.
Is it overkill for a normal bedroom?
If you sleep 10pm-6am with a streetlight outside, a budget triple-weave like NICETOWN does the job. Buy theater grade when daylight is the enemy — shift work, toddler naps, migraines.
How's the styling?
More conventional than the H.VERSAILTEX linen — solid colors, classic drape. It disappears into a room rather than making a statement.
Do they help with heat?
Yes — the liner layer measurably reduces summer solar gain and winter drafts through the glass. Not a substitute for insulation, but you feel it on west-facing windows.
